understanding output and optimal settings

[donna]

Greetings,
Purchased the Plustek OpticFilm 7600i with SilverFast AI Studio 6.62r4 hoping to archive in the best quality possible 20 years of slides and negatives. After 3 weeks of trial and error am still not sure about the relation between output and resolution as resulting in the dpi value. If I leave the output to the size of the frame (3.5 x 2.4) and slide the dpi slider to the higher values (after applying the various color and exposure corrections) will the result be the optimal all-purpose file, suitable for whatever size printing needed and of a very high quality?

As you can read, I'm an extreme novice and need hands-on advice as even after reading certain sections in the manual could not fathom the best method. In the beginning as a rule of thumb had scanned at an output of 30 x 20, Q factor 2.0 and lpi of 220 so the resulting dpi was 440..

Many thanks, Donna

Dear Donna,

The values in the input field for setting the image dimensions of
width and height of an original are automatically set by drawing
a scan frame on the prescan. Enter a quality factor (1.5 recommended) and the desired final size and SilverFast will calculate the
optimal resolution and scaling factor for you.

Best regards,
